Method
- Heat the oven to 375°F with a rack in the center.
- Whisk the cream of chicken soup, broth, 1/2 cup milk, garlic powder, black pepper, and thyme in a large bowl.
- Fold in the cooked chicken and frozen mixed vegetables. Spread the filling evenly in a 9-by-13-inch baking dish.
- Reserve the garlic-herb seasoning packet. Stir the biscuit mix, remaining 3/4 cup milk, and cheddar in a medium bowl just until no dry pockets remain.
- Drop the thick batter over the filling in 10 to 12 rough mounds, leaving small gaps between them.
- Bake uncovered for 25 minutes.
- Continue baking for 10 to 15 minutes, until the filling bubbles through the center gaps and the biscuit centers reach about 200°F. Stir the seasoning packet into the melted butter and brush it over the hot biscuits.
- Rest the casserole for 10 minutes before serving so the sauce can thicken.
Notes
Refrigerate leftovers for up to 4 days or freeze baked portions for up to 2 months, though the biscuit topping will soften. For make-ahead preparation, refrigerate the filling for up to 24 hours and mix the biscuit topping just before baking; cold filling may require 5 to 10 extra minutes.
